Weblocate and track the crack tip on the diffractometer using X-ray fluorescence. By comparing Laue patterns taken in unstrained material, the local grain orientations, three-dimensional strains and phases were computed at the grow-ing crack tip by analyzing the deviations in the spot loca-tions in diffraction patterns collected near the highly
WebThe crack tip stresses cause plastic deformation leading to energy consumption at the crack tip. This results in blunting of the crack, which means lesser energy is available for crack propagation and therefore increased fracture resistance.
